STOVEPIPE -FASTENER.

Application filed July 31, 1913. Serial No. 782,220.

To (ZZZ whom it may concern:

Be it known that I, LINCOLN A. Lown, a citizen of the United States,residing at Watson, in the county of Atchison and State of Missouri,have invented a new and useful Stovepipe-Fastener, of which thefollowing is a specification.

This invention relates to improvements in stove pipe fasteners and hasfor its object to provide a device of this class in which the pipecollar forms a part of the device.

A further object is to provide adjustable means whereby the distance thestove pipe projects into the chimney wall can be easily and readilyadjusted.

A further object is to provide a stove pipe fastener with a collarconnected thereto so that it will be practically impossible for thecollar to become separated from the chimney wall which would allow thesparks to pass therethrough, and furthermore to provide the collar witha plurality of apertures for the cooling of the collar and stove pipeadjacent the portion of the stovepipe which is inserted within thechimney wall.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed without de parting from the spirit of theinvention.

In the drawings accompanying this specification and forming a partthereof, the preferable form of my invention is illustrated, in whichFigure 1 is a view in longitudinal section of my improved device,showing the same secured to a stove pipe of which portions are brokenaway and in position within a chimney wall. Fig. 2 is a plan view of theattaching member illustrated in Fig. 1. Fig. 3 is a view in longitudinalsection of a somewhat modified form of the device. Fig. 4; is a frontview in elevation of the collar and sliding stop. Fig. 5 is a plan viewof the fastening member as illustrated in elevation Specification ofLetters Patent.

in Fig. 3'. Fig. 6 is a cross sectional view taken on the line 66 ofFig. 2.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 6 is a chimney wall insection and provided with the aperture 7 which provides for theinsertion of a stove pipe.

The fastener as illustrated in plan in Fig. 2 comprises a body portion 8in the form of an elongated strip preferably formed of metal andrivetedly connected to which is the two piece head 9. A two-piece head 9eX- tends at right angles to the body portion or shank 8 and constitutesan anchor for the fastening device by contacting with the inner surfaceof the chimney wall. The two pieces of the head being rivetedly securedto the shank, allows for the rotation thereof about the same as acenter, it being noted that the friction holding the same againstrotation is suflicient to prevent any accidental movement thereof. Thetwo pieces of the head are provided with the upstanding flanges 1Ostruck upwardly therefrom and which constitute a stop to prevent theexcessive insertion ofthe stove pipe 11 within the chimney flue whichwould tend to cut off the draft thereof with obvious disadvantages.Attention is called to the fact that the two parts of the head overlapand are connected by a rivet to the shank 8 as clearly illustrated inFig. 6 of the drawing.

The outer extremity of the shank 8 is provided with the curled end 12connected to which is the tension spring 13, the latter being by somemeans connected to the elbow 1% of the stove pipe. The last mentionedmeans in the present illustration being in the nature of a wire 15wrapped around the said elbow and bent upon itself as will be apparentfrom a reference to Fig. 1. Thus a suitable tension will be exerted uponthe shank 8 which will result in the stove pipe 11 being forced and heldrigidly within the chimney aperture 7. p

The shank 8 as clearly depicted in Fig. 2 is provided with thelongitudinal slot 16 for the reception of a securing, bolt 17 the latterbeing secured to a sliding stop 18.

Q 1,11ae1a T he sliding stop 18 comprises a plate with the overhangingears 19 which embrace the sides of the shank 8 and are guided forrelative motion thereby. The securing bolt 17 is provided with asuitable nut 20 thereon which is adapted to draw the sliding stop intofrictional engagement with the shank 8 to lock the stop in adjustedposition on the shank. A collar 21 is secured to the sliding stop bymeans of a suitable rivet 22, the stop in this instance being providedwit-l1 a downwardly extending flange 23 in order to effect suchconnection. The collar 21 is of the usual annular construction, and fitsover the stove pipe 11. A number of aper tures 24. are provided in thesaid collar for the cooling of the collar and the adjacent portions ofthe stove pipe, the collar acting in the nature of a radiatingflange asit is thought will be readily apparent. It has been found in practicethat unless the collar is rigidly secured to the stop, there is extremedanger of the collar drawing away from the chimney wall with the resultthat sparks are liable to work their way through the aperture 7 and tofall upon the carpet or floor with the resulting damages by fire, etc.In this connection it might be pointed out that the present applicationis a decided in'iprovement in this respect over my previous Patent#827,876.

It has been found advisable in some instances to provide means wherebythe length of pipe inserted within the chimney wall may be varied, thisbeing especially true when the chimney wall is of considerable thicknessand there is no necessity of the pipe extending entirely therethrough.Other advantages might be mentioned but however, it is thought that theyare readily apparent and in order to efiect this adjustability of thelength of pipe inserted a second longitudinal slot 25 is provided in theshank 8 as illustrated in Fig. 5 and slidably disposed therein is thebolt 26, forming an abutment against which the stove pipe 11 maycontact. An adjusted position cf the bolt is illustrated in Fig. 3 andshows the stove pipe 11 held at some little distance from the innersurface of the chimney wall. Also in the modified form as illus tratedin this figure the collar 21 is formed integral with the stop 18, thepeculiar advantage of the latter construction being that there will beno danger of the collar and sliding stop becoming separated due to afailing the rivet 22 or is there any likelihood of the two partsexperiencing a pivotal action. about the rivet 22 when the stove pipehas been removed from the collar. lso the construction is somewhatsimpler and presents a more neat appearance "By forming the head in twoparts, it allows the head to be collapsed for the in sertion thereof ina chimney wall opening of limited or restricted diameter. The parts ofthe head are again brought into their normal and extended position afterhaving negotiated the said opening.

Having thus fully described my invention, what I claim to be new andoriginal with me is 1. In a device of the class described, thecombination of a fastener including a shank and an outstanding head,said shank provided with a longitudinal slot, a. sliding stop mountedfor sliding movement upon said shank, securing means extending throughsaid slot and said sliding stop to lock the stop in adjusted position onthe shank, a collar connected to said stop, and means for securing astove pipe to said shank.

2. The combination with an apertured chimney wall and a stove pipe of afastener including an elongated shank provided with a longitudinal slot,and a head outstanding therefrom and contacting with the inner surfaceof the chimney wall, a tension spring, the remote extremity of saidshank being connected to said tension spring, the latter in turnconnected to the stove pipe, the said fastener head provided with anupstanding stop limiting the movement of the stove pipe, and a slidingstop provided with overhanging ears embracing the shank sides, securingmeans extending through the said stop and through the shank slot to lockthe stop in adjusted position on the shank, and collar connected to thesaid stop and con-- tacting with the external chimney surface.

3. In a device of the class described, the combination with an aperturedchimney wall and a stove pipe fitting therein, of a fastener includingan elongated shank provided with longitudinal slot therein, a headconnected to the said shank and outstanding therefrom engaging the innerchimney wall surface, a bolt rigidly secured to the shank adjacent thehead thereof and forming an adjustable abutment for the said stove pipeto regulate the length of pipe inserted within the said chimneyaperture, an apertured collar fitting over the said stove pipe andcontacting with the external chimney surface, a sliding stop projectingfrom said collar and comprising a plate with overhanging ears, the saidoverhanging ears overlapping the side edges of the said shank, and abolt extending through the said sliding stop, and through the shank slotand adapted to lock the stop against sliding motion with respect to theshank, and resilient means secured to the remote end of said shank andengaging the stove pipe for holding the same in rigid position withinthe said chimney aperture.

4. A stove pipe fastener comprising a shank and an outstanding head,means for securing said shank to a stove pipe, a stop mounted forsliding movement upon said shank, means engaging the said shank and Intestimony that I claim the foregoing sliding stop and adapted to lockthe stop as my own, I have hereto affixed my signain adjusted positionon the shank, and a ture in the presence of two Witnesses.
